Product details
Overview
ZXTN2007GTA from Diodes Incorporated is a 30V NPN medium-power low-saturation transistor in SOT223 package, rated for 7A continuous collector current and 20A peak pulse current, with VCE(SAT) ≤ 50mV at 1A and RSAT = 28mΩ at 6.5A - optimized for high-efficiency switching in DC-DC converters and MOSFET gate drivers.
For engineers reviewing the ZXTN2007GTA datasheet, ZXTN2007GTA pinout, ZXTN2007GTA application, or ZXTN2007GTA equivalent, key selection criteria include verified low on-resistance at high current, AEC-Q101 qualification for automotive-grade reliability, and thermal resistance (RθJA = 42°C/W on 52mm × 52mm 2oz copper) for sustained power-switching duty.
Technical Context
This NPN bipolar junction transistor operates as a saturated switch in medium-power linear and switching applications. Its design emphasizes low VCE(SAT) across wide current range (up to 20A), high hFE ≥ 100 at 20A, and robust safe operating area (SOA) up to 30V/7A DC.
It features a rugged SOT223 thermally enhanced plastic package with exposed collector tab, enabling direct PCB copper heatsinking. Thermal performance is specified under two mounting conditions: RθJA = 42°C/W (52mm × 52mm 2oz Cu) and 78°C/W (25mm × 25mm 1oz Cu), supporting flexible layout-dependent thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Maximum blocking voltage in common-emitter configuration; defines upper limit for DC-DC converter input or motor drive rail voltage. |
| IC (continuous) | 7 A - Sustained collector current capability; enables use in 5–10W power stages without forced air cooling. |
| VCE(SAT) @ 1A | < 50 mV - Low conduction loss at moderate load; reduces power dissipation to <50 mW at 1A, improving efficiency. |
| RSAT @ 6.5A | 28 mΩ - Equivalent on-resistance derived from VCE(SAT)/IC; supports high-current gate driving with minimal voltage droop. |
| hFE @ 20A | ≥ 30 - Minimum DC current gain at peak pulse current; ensures reliable base drive margin for fast turn-on in switching circuits. |
| fT | 140 MHz - Transition frequency; confirms suitability for high-speed switching up to ~10–20 MHz with adequate gain margin. |
| ESD HBM | 4000 V - Human Body Model rating; provides robustness against handling ESD during assembly and board-level integration. |
Pinout & Package
Package: SOT223 - surface-mount, thermally enhanced plastic case with exposed collector tab (pin 3) for direct PCB copper heatsinking; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Reference node for base drive; connected to ground or low-side return path in switching topologies. |
| Pin 2 (Base) | Control input | Receives current-limited drive signal; requires IB = 100mA for full saturation at IC = 1A (IC/IB = 10). |
| Pin 3 (Collector) | Power output / heat sink | Main current path and primary thermal interface; electrically tied to PCB copper pour for thermal dissipation. |
| Tab (Collector) | Collector extension | Exposed metal pad on underside; must be soldered to large copper area to achieve RθJA = 42°C/W rating. |
Key Features
| Feature | Design Value |
|---|---|
| Low saturation voltage | VCE(SAT) ≤ 35 mV typical at IC = 1A - minimizes conduction loss in high-duty-cycle switching applications. |
| High-current gain retention | hFE ≥ 30 at IC = 20A - maintains control authority during transient overloads, reducing required base drive power. |
| Thermally optimized package | SOT223 with exposed collector tab - enables 3.0 W continuous power dissipation with standard PCB heatsinking (no heatsink required). |
| AEC-Q101 qualification | Automotive-grade reliability testing passed - suitable for under-hood and infotainment power stages requiring extended temperature (-55°C to +150°C) operation. |
Applications
| DC-DC Converters | MOSFET Gate Drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2010GTA | Higher VCEO = 40V, same SOT223 package, but VCE(SAT) = 65mV @ 1A (30% higher loss) | Better for 36V nominal systems; less efficient at 12–24V rails due to higher saturation voltage | Select when higher breakdown margin is critical and thermal headroom allows for increased loss. |
| MMBT4401LT1G | Lower IC = 600mA, SOT-23 package, VCE(SAT) = 750mV @ 150mA - not scalable to 7A | Only suitable for signal-level or low-power switching; cannot replace ZXTN2007GTA in power stages | Use only for logic-level interfacing or bias networks - not a functional substitute in power applications. |
Compared with ZXTN2007GTA, ZXTN2010GTA trades lower conduction loss for higher voltage rating, while MMBT4401LT1G lacks both current capacity and thermal capability - making ZXTN2007GTA uniquely suited for 7A, 30V saturated switching where efficiency and reliability are co-prioritized.

FAQ
Is ZXTN2007GTA pin-compatible with other SOT223 NPN transistors?
No - while the SOT223 footprint is standardized, pin assignment (Emitter/Base/Collector) varies across manufacturers and product families. ZXTN2007GTA uses the Diodes-specific pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (tab). Always verify layout against the official AP02002 package drawing before PCB design.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation up to this limit when thermal design meets the specified RθJA = 42°C/W condition (52mm × 52mm 2oz Cu). Derating begins above +25°C ambient, with linear reduction of PD to zero at +125°C ambient under that mounting condition.
Can ZXTN2007GTA be used in linear regulator applications?
Yes - its high hFE (≥100 at 1A) and low VCE(SAT) support use as a pass transistor in adjustable linear regulators, but power dissipation must remain within the SOA limits. At 7A output, even 100mV dropout yields 0.7W loss - acceptable only with adequate heatsinking and derated ambient temperature.
Does ZXTN2007GTA require a base resistor in all switching configurations?
Yes - base current must be actively limited to prevent damage and ensure predictable saturation. For IC = 7A, recommended IB = 300mA (IC/IB ≈ 23), requiring a low-impedance driver and appropriate series resistance to avoid exceeding VBE(SAT) = 1.13V and maintain safe power dissipation in the base region.
